Palm Bay Water Hardness & Quality Report (2026)

Palm Bay, Florida, the largest city in Brevard County on Florida's Atlantic Space Coast, draws its municipal water supply primarily from groundwater wells tapping the Floridan Aquifer System (specifically the Upper Floridan Aquifer) via Palm Bay Utility Systems wellfields in Brevard County. The Floridan Aquifer — one of the most productive aquifer systems in the world — is a thick sequence of Paleogene marine carbonate rock underlying most of Florida. In Brevard County, the aquifer draws from the Eocene Ocala Limestone and Avon Park Formation dolomite at various depths. Water hardness measures 164 mg/L — classified as hard.

Palm Bay's hard supply reflects the Floridan Aquifer's regional carbonate character in Brevard County. The Upper Floridan Aquifer here is confined beneath low-permeability clays and draws from the Eocene Ocala Group limestone — a highly pure, porous bioclastic and crystalline limestone — and from the Avon Park Formation dolomite (an older Eocene unit). These ancient marine carbonates readily dissolve calcium bicarbonate into confined aquifer water. Brevard County's wellfield zone shows somewhat lower hardness than the coastal southeast Florida Biscayne Aquifer zones, reflecting the Floridan's deeper confined character and somewhat different carbonate chemistry, but the result is still firmly in the hard water range.

At 164 mg/L, Palm Bay residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, shower glass, and tile within weeks — monthly descaling with citric acid solution is standard maintenance. Dishwashers produce better results with rinse-aid, and water heaters benefit from annual element inspection for scale accumulation. Palm Bay Utility Systems consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
